Three aspiring biophotonics entrepreneurs working on potentially life-saving techniques for detecting cancer and malaria have won some expert help in moving their ideas to market.As winners of a Biophotonics Startup Challenge at SPIE Photonics West in January, the three are being sponsored by Newport Spectra-Physics to attend the Biomedical Engineering Entrepreneurship Academy at the University of California, Davis, next summer.

A cheek-swab test for lung cancer would be "a paradigm shift, in that we don't need to examine the tumor itself to determine the presence of cancer," said Hariharan Subramanian (Northwestern University) of the technique he and colleagues including Hemant Roy (North Shore University Health System) and Vadim Backman (Northwestern) have developed.

A system based on total internal reflection principles that can pick up signs of early-stage breast tumors at a depth of 3 cm earned Chang Won (Temple University) a place at the entrepreneurship academy. Won…

The work of rebuilding after last week’s powerful earthquakes and tsunami in Japan is underway already, even as aid organizations reach out to the injured and those whose homes were damaged or destroyed. Efforts to stabilize nuclear reactors continue amid continuing earthquakes and aftershocks around the country.

Authored by SPIE, the international society for optics and photonics, the Photonics for a Better World blog focuses on research news and the many ways technologies are applied to advance science and improve quality of life, and on the people who make that happen.
